Powering down the Pfam website
On October 5th, we will start redirecting the traffic from Pfam (pfam.xfam.org) to InterPro (www.ebi.ac.uk/interpro). The Pfam website will be available at pfam-legacy.xfam.org until January 2023, when it will be decommissioned. You can read more about the sunset period in our blog post.

Stathmin Edit Wikipedia article

Stathmin (or oncoprotein 18), an inhibitor of microtubule formation, as highly expressed in the lateral nucleus (LA) of the amygdala as well as in the thalamic and cortical structures that send information to the LA about the conditioned (learned fear) and unconditioned stimuli (innate fear). Whole-cell recordings from amygdala slices that are isolated from stathmin knockout mice show deficits in spike-timing-dependent long-term potentiation (LTP). The knockout mice also exhibit decreased memory in amygdala-dependent fear conditioning and fail to recognize danger in innately aversive environments. By contrast, these mice do not show deficits in the water maze, a spatial task dependent on the hippocampus, where stathmin is not normally expressed. We therefore conclude that stathmin is required for the induction of LTP in afferent inputs to the amygdala and is essential in regulating both innate and learned fear.

tubulin-colchicine-vinblastine: stathmin-like domain complex

Stathmin is a ubiquitous phosphorylated protein thought to act as an intracellular relay for diverse regulatory pathways,[1] functioning through a variety of second messengers. Its phosphorylation and gene expression are regulated throughout development [2] and in response to extracellular signals regulating cell proliferation, differentiation and function.[3] Stathmin, and the related proteins SCG10 and XB3, contain a N-terminal domain (XB3 contains an additional N-terminal hydrophobic region), a 78 amino acid coiled-coil region, and a short C-terminal domain.

Stathmin family Provide feedback

The Stathmin family of proteins play an important role in the regulation of the microtubule cytoskeleton. They regulate microtubule dynamics by promoting depolymerization of microtubules and/or preventing polymerisation of tubulin heterodimers [1].

InterPro entry IPR000956

Stathmin [ PUBMED:1957351 ] (from the Greek 'stathmos' which means relay), is a ubiquitous intracellular protein, present in a variety of phosphorylated forms. It is involved in the regulation of the microtubule (MT) filament system by destabilising microtubules. It prevents assembly and promotes disassembly of microtubules [ PUBMED:14598370 ]. However, when phosphorylated, its destabilisation ability is significantly reduced [ PUBMED:11160824 ].

The stathmin family also includes:

  • Stathmin 2 (Protein SCG10); a neuron-specific, membrane-associated protein that accumulates in the growth cones of developing neurons. It is highly similar in its sequence to stathmin, but differs in that it contains an additional N-terminal hydrophobic segment of 32 residues which is probably responsible for its interaction with membranes.
  • Stathmin 3 (SCG10-like protein; SCLIP) [ PUBMED:9603203 ]; a protein specifically expressed in neurons.
  • Stathmin 4 (Stathmin-like protein B3); which contains an additional N- terminal hydrophobic domain [ PUBMED:9342231 ].

These proteins possess a stathmin-like domain (SLD) with various N-terminal extensions. SLD is a highly conserved domain of 149 amino acid residues. Structurally, it consists of an N-terminal domain of about 45 residues followed by a 78 residue alpha-helical domain consisting of a heptad repeat coiled coil structure and a C-terminal domain of 25 residues [ PUBMED:15014504 , PUBMED:11278715 ]. The SLD binds two tubulins arranged longitudinally, head-to-tail, in protofilament-like complexes.

We store a range of different sequence alignments for families. As well as the seed alignment from which the family is built, we provide the full alignment, generated by searching the sequence database (reference proteomes) using the family HMM. We also generate alignments using four representative proteomes (RP) sets and the UniProtKB sequence database. More...

View options

We make a range of alignments for each Pfam-A family. You can see a description of each above. You can view these alignments in various ways but please note that some types of alignment are never generated while others may not be available for all families, most commonly because the alignments are too large to handle.

This page displays the phylogenetic tree for this family's seed alignment. We use FastTree to calculate neighbour join trees with a local bootstrap based on 100 resamples (shown next to the tree nodes). FastTree calculates approximately-maximum-likelihood phylogenetic trees from our seed alignment.

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the Stathmin domain has been found. There are 222 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein sequence.
